Meta-Analysis of Meta-Analyses

This meta-analysis of meta-analyses just appeared in a major radiology journal:
Informative Reporting of Systematic Reviews in Radiology  
Radiology November 2013 269:2 313-314 
In this issue of Radiology, Tunis and colleagues report on a study designed to evaluate whether the completeness of reporting of systematic reviews and meta-analyses in 11 radiology journals improved between 2007 and 2011; reporting has improved, albeit slowly, but attributing the slow change entirely to Preferred Reporting Items for Systematic Reviews and Meta-Analyses may be too generous.
